His brother Edward Daniel said Marin-Garibay's arrest has brought "some degree of relief" to their family.

"If this would have just been an innocent accident, this would have been easier to take," Edward Daniel said. "But to just get in that truck and keep going, not even bother to get out to check."

"Why didn't you stop?" he wondered Wednesday morning, when asked what he would say to the man accused of taking his brother's life. "You left him in the street and didn't even try to find out was he alive, dead."

"Now you're going to have to pay, face the consequences of this," he added.

Officer Daniel's sister, Doris Thomas said they worried constantly about their brother's safety in the field, but said law enforcement was what he was born to do.

A husband and father of three adult children, Officer Daniel was devoted to his family.

"He was a good man," Edward Daniel said. "He loved his family. He loved his kids." He remembered weeks his brother spent taking his children on college visits and coaching his sons' little league baseball teams.

Officer Daniel retired after 26 years with the DeKalb County Police force, but his brother knew he was "too young, had too much energy" to just stay at home. Officer Daniel soon began working in Henry County, to continue doing what he loved: helping others.

"He would do anything for you," Edward Daniel said.

"He'd give you the shirt off his back," Thomas said. "If there's any way he could help you, he'd help you."
